25 Amazing Photographs That Capture Astronauts Make Walking in Space

Astronauts make walking in space look easy. But astronauts use a lot of tools and equipment to help them do their job and stay safe. This gallery is filled with photos of astronauts on spacewalks. The pictures show tools like handrails and foot restraints that astronauts use to move around on spacewalks. They show some of the work astronauts do on spacewalks and how spacewalkers stay safe.


The Soviets beat Americans to spacewalking. On March 18, 1965, Aleksey Leonov became the first human to walk in space. The image is a still from the external movie camera attached to his vessel, the Soviet Voskhod 2.

Edward White is seen floating outside the Gemini 4 capsule in 1965.

Mission STS-41b marked the first checkout of the Manned Maneuvering Unit (MMU) and Manipulator Foot Restraint (MFR). McCandless made the first untethered free flight on each of the two MMUs carried on board, thereby becoming the first person ever to make an untethered spacewalk.

Bruce McCandless. Alone in the Universe.

Astronaut Robert L. Stewart becomes the second man to participate in an untethered EVA using the MMU. He was also the first member of the U.S. Army to go into space.

Astronaut Mark Lee testing the Simplified Aid for EVA Rescue (SAFER) system for NASA in 1994. SAFER is a backpack propulsion unit that incorporates small nitrogen thrusters controlled by hand and moderated by computer. Pictured, Lee jets about the bay of Space Shuttle Discovery, over 200 kilometers above Earth in the first untethered space walk in ten years. Lee was not in danger -- the shuttle could have been used to retrieve him. SAFER, smaller than the Manned Maneuvering Unit, is designed as a backup system to help astronauts in the unlikely event that they become too separated from their work outside the International Space Station.

Our favorite redditing Astronaut, Chris Hadfield.

Astronaut Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), is seen near the Canadarm2 as the new robotics tool for the International Space Station (ISS) grasps the Spacelab pallet. Hadfield participated in two days of extravehicular activity (EVA) on the STS-100 mission.

Astronaut Carl Walz waves at his colleagues from the aft end of the Space Shuttle Discovery's payload bay. During this 1993 spacewalk, Walz evaluated tools, tethers, and a foot restraint designed for use in a weightless environment while orbiting Planet Earth.

In 1984, high above the Earth's surface, an astronaut captured a satellite. It was the second satellite captured that mission. Pictured above, astronaut Dale A. Gardner flies free using the Manned Maneuvering Unit and begins to attach a control device dubbed the Stinger to the rotating Westar 6 satellite. Communications satellite Westar 6 had suffered a rocket malfunction that left it unable to reach its intended high geosynchronous orbit. Both the previously caught Palapa B-2 satellite and the Westar 6 satellite were guided into the cargo bay of the Space Shuttle Discovery and returned to Earth. Westar 6 was subsequently refurbished and sold.

Astronaut Dale A. Gardner, having just completed the major portion of his second extravehicular activity (EVA) period in three days, holds up a "For Sale" sign refering to the two satellites, Palapa B-2 and Westar 6 that they retrieved from orbit after their Payload Assist Modules (PAM) failed to fire. Astronaut Joseph P. Allen IV, who also participated in the two EVAs, is reflected in Gardner's helmet visor. A portion of each of two recovered satellites is in the lower right corner, with Westar 6 nearer Discovery's aft.

In low Earth orbit there is not enough atmosphere to diffuse and scatter sunlight, so shadows are black and the sky is dark - even when the Sun shines. The harsh lighting produced this dramatic effect as mission specialist Gregory Harbaugh photographed colleague Joseph Tanner during their second spacewalk to service the Hubble Space Telescope in February 1997. The aft section of the Space Shuttle Discovery is visible in the background with the Sun hanging over a delicate crescent of the Earth's limb. A checklist is attached to Tanner's left arm, and Harbaugh's reflection is just visible in Tanner's visor.

NASA astronaut Sunita Williams, Expedition 32 flight engineer, appears to touch the bright sun during the mission’s third spacewalk on Sept. 5, 2012.

Astronauts Clay Anderson (left), Expedition 15 flight engineer; and Rick Mastracchio, STS-118 mission specialist, participate in the mission's third planned session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the 5-hour, 28-minute spacewalk, Mastracchio and Anderson relocated the S-Band Antenna Sub-Assembly from Port 6 (P6) to Port 1 (P1) truss, installed a new transponder on P1 and retrieved the P6 transponder.

Astronaut Rick Mastracchio, STS-118 mission specialist, participates in the mission's third planned session of extravehicular activity as construction and maintenance continue on the International Space Station. During the 5-hour, 28-minute spacewalk, Mastracchio and astronaut Clay Anderson (out of frame), Expedition 15 flight engineer, relocated the S-Band Antenna Sub-Assembly from Port 6 (P6) to Port 1 (P1) truss, installed a new transponder on P1 and retrieved the P6 transponder.

Mission Specialist Winston Scott is seen from inside orbiter Columbia as he conducts the second extravehicular activity on mission STS-87 in 1993.

Expedition 20 flight engineer Nicole Stott participates in the STS-128 mission's first spacewalk as construction and maintenance continue on the International Space Station. During the six-hour, 35-minute spacewalk, Stott and astronaut Danny Olivas (out of frame) removed an empty ammonia tank from the station's truss and temporarily stowed it on the station's robotic arm. Olivas and Stott also retrieved the European Technology Exposure Facility and Materials International Space Station Experiment from the Columbus laboratory module and installed them on Discovery's payload bay for return.

Astronaut John Grunsfeld performs work on the Hubble Space Telescope during the first of five STS-125 spacewalks.

This picture shows two astronauts, Robert L. Curbeam, Jr. (left) and Christer Fuglesang while conducting an extravehicular activity outside the International Space Station as part of the STS-116 mission. On the background is the Cook Strait in New Zealand and the Pacific Ocean.

Astronaut Rex J. Walheim, STS-110 mission specialist, translates along the Destiny laboratory on the International Space Station (ISS) during the third scheduled session of extravehicular activity (EVA) for the STS-110 mission.
